Description

Electronic dumper truck

The utility model relates to a kind of transportation device, particularly a kind of electronic dumper truck.

At present, as short-range electric transportation instrument, adopt the dolly of direct motor drive band hopper to finish to connect material more, transport, discharging work, its charge cask mainly contains the tilt bed hopper and takes out end formula hopper two major types.It is tight that the tilt bed hopper has the bottom, water-tight and non-leakage fluid slurry, and topple over advantages such as clean easily, but the poor stability of this type of hopper, and transport when containing fluid bulk cargo or slurry, require hopper very steady, spread out from hopper to prevent material, and, hopper will arrive fixing feed opening and connect material, and the off-position of hopper will quite accurately just can avoid spattering material, otherwise not only can be poured on the outside to material, hopper and feed opening are collided, damage hopper.It is fixing onboard to take out end formula hopper, the good stability of hopper, but only be applicable to the shipment siccative, should not be used to load and transport wet feed or slurry, have the gap inevitably because take out between the removable bottom of end formula hopper and the headwall, flowing material oozes out easily, and easily blocks the hopper mouth.

The purpose of this utility model be to provide a kind of that can contain that solid again can the splendid attire flowing material, have the autostable hopper and the electronic dumper truck of overload defencive function arranged.

The purpose of this utility model is achieved in that and is set with rotating shaft 4 on the rotary bracket 2, hopper 1 is packed on the rotary bracket 2, sprocket wheel 3 is affixed with rotating shaft 4, sprocket wheel 7 is affixed with rotating shaft 6, sprocket wheel 3 and sprocket wheel 7 are equipped with reductor 8, drg 9, electrical motor 11 by chain 5 links on the same axis of rotating shaft 6.The side on hopper 1 top also is provided with elastic force energy disperser 12, and the rotating shaft 3 of carriage 2 has eccentric distance e with the center of gravity of hopper 1.Between electrical motor 11 and reductor 8, settle a friction disk type safety coupling 10.

The utility model has the advantages that: it can contain solid matter, again can the splendid attire flowing material, and have the function of overload protection and autostable hopper, and simple in structure, running is reliably, the angle of inclination is big, safety good, degree of automation is high.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a perspective view of the present utility model.

1-hopper, 2-carriage, 3-driven sprocket, 4-rotating shaft, 5-chain, 6-rotating shaft, 7-drive sprocket, 8-reductor, 9-drg, 10-safety coupling, 11-electrical motor, 12-elastic force energy disperser among the figure.

Embodiment: as shown in Figure 1, hopper 1 usefulness bolt is packed on the rotary bracket 2, when carriage 2 rotates, drives hopper 1 and rotates, and finishes and topples over discharging and homing action.The rotating shaft 4 of carriage 2 has a bigger eccentric amount e with the center of gravity of hopper 1, and the gravity of hopper 1 produces a moment to center of gyration.This moment makes driving chain 5 tensionings, eliminated the gap of chain 5 and transmission device, in order to guarantee enough tensile forces, also be provided with an elastic force energy disperser 12 that enough strokes are arranged in the side on hopper 1 top, it had both increased the tensile force of chain 5, buffer action is arranged again, eliminate the inertia of hopper 1 and carriage 2.Hopper 1 tumble and the process that resets in, the stressed side tensioning that the gravity of hopper 1 makes chain 5 all the time realizes the transmission of no gap.Therefore, upset does not steadily have and impacts.Under chain 5 drove, the angle of inclination of hopper 1 reached 160 °, and the material in the bucket can successfully be toppled over totally no retentate.

For guaranteeing that reductor 8 is when stopping, can not produce reverse fine motion because of the tension force of chain 5, on the input shaft of reductor 8, be provided with drg 9, the braking force of drg 9 can prevent that hopper 1 from rotating under gravity or elastic force effect, make hopper 1 more firm, even there is other external force to disturb, can unstability yet.Simultaneously, drg 9 can also make hopper 1 in time stop, and is parked in ideal position exactly.In the present embodiment, to make volume be 2m to hopper 1 ³, load carrying ability is the big hopper of 5T, so in a single day the heavy amount jam occurs in operation process, will cause chain rupture or damage driving device.In order to prevent this class accident, we settle a friction disk type safety coupling 10 between electrical motor 11 and reductor 8, as long as the load that occurs exceeding the quata, safety coupling 10 will produce slide relative, avoids equipment breakdown.

In sum, the utility model has made full use of tilting hopper running failure-free advantage by adopting the unitized construction of carriage and hopper, utilizes the characteristics of carriage good rigidly simultaneously again, and it is reliable to make it stability of rotation.Hopper just is used for the splendid attire material, when volume is big, also needn't do complicatedly, heavy.Hopper 1 will bear the impact friction of material, and is more fragile, in case be damaged, also only need to change hopper 1, and need not change carriage 2.Because of hopper 1 is to be fixed by bolts on the carriage 2, change also very convenient.If rotating shaft directly is fixed on the hopper, then the structure of hopper must be done to such an extent that very solidly could guarantee enough rigidity, and this has just increased the complexity and the weight of hopper widely.Otherwise can cause axes of rotation skew because rigidity is not enough, the rotation of hopper just is easy to generate fault; Hopper just must connect rotating shaft and will scrap together in case damaged, and during the dismounting hopper, connecting shaft holds, sprocket wheel all will be dismantled, and repair and maintenance bothers very much, adopts the discrete structure of hopper 1 and carriage 2, has just overcome above-mentioned difficulties.The utility model is not provided with independent detent mechanism, but the location of realizing hopper 1 by structure design cleverly.Its adopts with the gravity of hopper 1, the elastic force tension chain 5 of elastic force energy disperser 12, and with the brake-force balance of drg 9, thereby eliminate gap in chain and the transmission device, keep the stable of hopper, hopper 1 is in operation do not have and rocks, the location is reliable when stopping.It has advantage simple in structure, that running is reliable, the angle of inclination is big, safety good, degree of automation is high, is a kind of new and effective transportation device.
